Description

Printing screen plate with graphics and method of making the same

The invention relates to a structure of a printing screen and a manufacturing method thereof, in particular to a printing screen which can adjust the angles of warp and weft lines in conjunction with graphics.

In the prior art, a printing screen is usually used to print the electrode pattern of the solar cell, and the pattern required at present is getting more and more fine. However, the interlaced knots of the warp and weft lines of the printing screen are prone to blockage. Therefore, in the current conventional technology, a knotless design is adopted, and the graphics are opened in two parallel warp or weft lines, which increases the ink permeability. question.

However, in the conventional screen structure, since the opening pattern 901 is the solar finger line shown in FIG. 1 , the left straight portion of the L-shaped pattern is perpendicular to the weft line. When printing, the ink is blocked by the weft 803, so that the printed pattern has large fluctuations, and it is easy to make the printed finger electrode pattern impedance too high, and the power generation efficiency is low.

In addition, if the warp 801 in the opening pattern 901 is removed, only the weft 803 will remain in the bottom edge of the L-shape of the opening pattern 901, which will cause the ink to be blocked by the weft 803 during printing. The output pattern impedance is too high and the power generation efficiency is low.

In the central area or other places, only the warp 201 or the weft 203 is included in the predetermined yarn removal pattern area A1 and the opening pattern 301, and FIG. 2 shows the state where only the weft 203 is included. In addition, the area of the predetermined yarn removal pattern area A1 is 2 to 20 times the area of the opening pattern 301 to facilitate the formation of the opening pattern 301 . Furthermore, in an embodiment of the present invention, the warp threads 201 or the weft threads 203 may be made of metal, such as stainless steel or tungsten steel. It should be understood that the L-shaped opening pattern 301 in FIG. 2 has been adjusted for its setting position for convenience of illustration, and it may actually be located in the center of the predetermined yarn removing pattern area A1 or other places.
